Talk:Streptococcus salivarius
From Wikipedia, the free encyclopedia
google says it is pathogenic. Mikkalai 09:05, 13 Feb 2005 (UTC)
- No, Google says it's used in yogurt manufacturing. I removed the dispute tag. — Brim 10:19, Feb 13, 2005 (UTC)
- No, google says it is pathogenic as well. Accuracy tag placed. This is not the same as "dispute". I am not disputing what is written. I am saying that This pathogenicity is too important issue, so that the article becomes inaccurate. In the present form the article is like saying that hydrocyanic acid is the thingy that makes the cherry wine so tasty. Mikkalai 18:59, 13 Feb 2005 (UTC)
- Could you be so kind as to provide a link to article that says S. salivarius is pathogenic? Everything that I've come across says that it's a part of the normal human oropharyngeal flora and is used in the manufacture of yogurt. — Brim 00:14, Feb 14, 2005 (UTC)

SECTION II - HEALTH HAZARD
PATHOGENICITY: Organisms colonize upper respiratory tract within first few hours after birth and are normal inhabitant of oral cavity, oropharynx and upper respiratory tract; infrequently pathogenic; Viridans streptococci species cause most dental caries and are the most frequent cause of subacute native valve bacterial endocarditis, typically associated with dental procedures; S. salivarius may cause septicemia in neutropenic patients
EPIDEMIOLOGY: World wide; Dental caries common; persons with previously damaged heart valves are susceptible
HOST RANGE: Humans
INFECTIOUS DOSE: Not known
MODE OF TRANSMISSION: Normal inhabitant of upper respiratory tract - trauma (dental work, brushing teeth, etc.) results in organisms entering into the blood stream
INCUBATION PERIOD: Not known
COMMUNICABILITY: Not transferred from person-to-person
General Internet USER Response: GUYS Brim is probably more 'right' than you are Mikkalai. Salivarius is NATURAL to the human mouth cavity and is [practically] the exclusive lactobacilli found in the human mouth soon after birth and prior to the 1st teething of the child. Once the child teeths other bactrial flora start to dominate (S.Mutans, Acidophilus, Thermophilus, etc.). While I'm not disputing the Salivarius has been found in Heart Valves, the pathogenity is still in question. You should be made aware the S. Salivarius is the LIVE active ingredient in a mouthwash approved by regulators in the EU, UK, Australia and New Zealand for NON-PRESCRIPTION daily use. This particular mouthwash is being marketed for fighting Chronic Halitosis by using Salivarius bacteria to kill and starve the Anaerobic Sulfurous Gas producing bacteria that cause halitosis. If this bacteria was such a pathogen, Mikkalai, then regulators would not allow it be available freely and without a prescription.
Nonetheless Mikkalai has got a legitmate point about this particular bacterial species being implicated in Heart Valve infections. Anybody (professional researcher hopefully), that could shed light on the heart valve issue would be helpful. Please remember that many 'benign' microoganisms that exist in our bodies can become pathogenic under certain circumstances, that does not make these organisms pathogenic in general, and heart valves are not natural structures in our bodies. Quite frankly, we don't know if a flaw in the design of those heart valves may have contributed to the Salivirius colonies taking hold in the valves.

D.Roy: Streptococcus thermophilus is now considered a full-fledge species and is no longer considered a subspecies of S. thermophilus. there are at least 3 complete genome of S. thermophilus out there (see ncbi pubmed) and it was shown that Thermophilus as no intact gene associated with pathogenicity.
On another subject, S. salvarius is NOT implicated with tooth decay, S. mutans is respnsible for that. furthermore, Streptococcus is not a lactobacilli... its a streptococcus, i.e. a coccus, or roud shaped bacteria in short chain (hence the "strepto") lactobacilli are rod shaped bacteria. Finally, S. salivarius is an opportunistic pathogen, i.e. by itself it wont do much but given the chance (immunodeficient patient) it may do some harm.
D.Roy (2006/02/01): S. salivarius is not involved in tooth decay, S. mutans is, so I changed that information in the article. Furthermore, I strongly believe that S. themophilus and S. salivarius should be splitted in two different article, since both are very different organism.
I also changed the statement where it was said that S. salivarius is used in cheese and yogurt production, Its the work of S. thermophilus.
Foor those who know how to do it... S. thermophilus should be erased from this section and added to its own section titled Streptococcus thermophilus... D. Roy
